Appendix J – Timed Messaging Function
The Timed Messaging Function is designed to allow the
WaveWare Paging System
to be used for purposes of
automatically transmitting predefined messages upon timer related conditions. The Timed Messaging Function can
be activated during the process of programming the pager database using the WaveWare Paging Encoder Setup
software. The Timed Messaging Function is available in all modes of operation. The Timed Messaging Function
operates as follows:
Concurrent with the encoder monitoring the serial port for normal paging messages, the Timed Messaging Function
uses an internal 1.06 minute timer cycle to determine whether or not to transmit predefined messages. If the timer is
not reset by the host system while the Timed Messaging Function is active, the paging system will transmit
predefined messages as defined in the pager database configuration. The timer is reset under the following
conditions if the Timed Messaging Function is active:
Reception of a valid TAP protocol formatted control string on the serial port
Reception of the ATI<CR> control string on the serial port
When programming the
WaveWare Paging System
pager database, each of the ten pager groups of up to 20 pagers
per group in the pager database can be associated with the Timed Messaging Function and associated with one of up
to 15 configurable predefined messages of up to 60 characters in length. If a pager group has the Timed Messaging
Function active, all pagers in that pager group will receive a predefined message.
Some practical applications of the Timed Messaging Function are as follows:
In mission critical environments, the Timed Messaging Function can be used to monitor the host system and
notify someone's pager that the host system needs attention. To accomplish this, program the host control
software to output a TAP message or the ATI<CR> command every minute. If the host gets disconnected from
the paging system or the host stops functioning, the Host Monitoring Function will come into play.
Use the Timed Messaging Function in a supervisory controlled paging system environment to allow other
portions of the system to know that the paging system's encoder and transceiver are functioning properly, by
monitoring for the predefined message being transmitted automatically by the paging system.
